CHARLES 1F'. RAYNAUID, 0F SAN FRANCISCO, CALIFORNIA, ASSIGNOR TO THE PACIFIC FOLDING BOX FACTORY, INC., @ESAN FRANCISCO, CALIFRNIA, A COBIORATON OF Specification of Letters Patent.

CARTON.

Application filed April 1, 1914. Serial No. $28,336.

To all 107mm t may concern Be it known that l, CHARLEs F. RAYNAUD, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful improvements in Cartons, of which the following is a speciiication'.

My invention relates to an improvement in cartons, or cardboard boxes used for packing and transporting merchandise, and is especially adapted to hold bottles.

@ne of the objects of my invention is to provide a carton or case which is divided into a plurality of cells or compartments and in which the walls and partitions are cut from a single sheet and folded to form the carton.

Another object is to arrange the parts so that the sides and partitions are formed by a series of parallel folds or creases in a single rectangular sheet, thereby reducing the waste or loss of material to a minimum.

il. further purpose of my invention is to provide a cellular carton which may be completely formed at the factory and then shipped in compact substantially flat condition, `thereby economizing space in transportation and storage.

In the accompanyingv drawings which illustrate an embodiment of my invention, Figure l is a plan of a blank cut and creased to forni a two-cell carton; Fig. 2 is a perspective view of the same folded but before the parts are united at the seam or joint;

Fig. 3 is a partially collapsed end View of the completed cart-on showing the manner of folding for storage or shipment; Fig. 4 is a cross section, partly broken away, on the line of Fig. 5; Fig. 5 is a partial perspective view of the completed carton with the end or closure flaps in locked position; F ig. 6 shows in plan the blank for a three-cell carton; Fig. 7 is a perspective view of the same showing the manner of folding the sides and partitions; Fig. 8 is a transverse sectional view; and Fig. 9 is a partial perspective view of the saine showing the manner of forming the seam' orljoint.

The blank shown in Fig. l, is cut from a sheet of cardboard or similar material and is substantially rectangular in outline, there being no waste, save for the notched corners at one end. The top, bottom, sides and partition are formed from a single rectangular shape by means of a series of parallel creases, indicated by dotted lines, forming bending joints. The bottom l, is the intermediate member flanked upon either side by the sides 2, 3, the top being formed of two portions, 4, 4", lying upon the outs-ide of the respective side members, the seam flap G, being glued or otherwise secured to bring the outer edges of the top members together into an integral structure. The partition member 5, forms a continuation or extension of one of the top members 4:, being united thereto by a bending joint or crease at the seam line.

After the blank has been cut as indicated to form the\valls of the carton and the end flaps la, 2a, 3, etc., provided with slits 7, the parts are bent up, as indicated in Fig. 2,-upon the creases or bending joints at the intersect-ing edges, the partition 5, being lbent downwardly to separate the carton into its compartments or cells, and the seam flap 6 is then glued or pasted to the outer side or margin of the partition member, the two top parts l, a being made flush. Tofurther strengthen and increase, the rigidity of the glued joint the flap members l upon one side of the joint are provided with seam flaps 6a which overlap the end flaps el upon the other side of the seam and are glued or .pasted thereto, the interlocked flaps forming a unitary end closure for the carton. This seam in the end flaps makes the top end flap anintegral structure and relieves the seam or joint along the seam iiap 6 of strains to which it would .otherwise be subjected. It will be observed that this intermediate pasted seam or joint extending longitudinally through the intermediate portion of th'etop of the `carton constitutes, in fact, a reinforcement o r stitfening rib and adds materially to the rigidity of the structure. rlhe partition inember extends inwardly along the entire line of the joint and constitutes a strut vor brace for the joint, relieving the joint of the strains and stresses which would tend to rupture the joint.

After the parts have been folded and glued as above described, the end flaps 2a, 3, are bent inwardly, the flaps t and ll being turned down thereover and locked in position by passing the ears lb, through the slits 7, as indicated in Fig. 5.

After the carton has been formed in the manner above described, it may be collapsed into Hat form, as indicated in Fig. 3,-in

ico

order that the cartons may be compactly arranged for storing or shipping in knock down condition. 'inasmuch as the partition member 5 is reeaat its outer edge, it may be laid out parallel. with the top member and be attened out against it. lt is. a decided advantage to be able to thus flatten the completed carton and yet have it at all times in condition to be instantly shifted into the position shown in Figu l, readyto receive the bottles or other merchandise which. is to be packed therein. rllhis is accomplished the more readily by reason of the fact that the partition member 5 is secured only along one longitudinal edge and is, therefore, free to be swung or `bent toward the top member when the carton is to be collapsed. and downwardly into the intermediate position shown in Figs. 2 'and 4- when the carton is to be opened into operative positionB ln Figs. 6 to "9, inclusive, .ll have illustrated my invention applied to a carton having three cells or compartments. The construction. is substantially the same as that above described and diiers therefrom mainly in having the partition member 5, which forms an extension oi' the top member 4, creased longitudinally, as indicated by dotted lines in Fig, 6, to form the partition members 5a and 5C connected by the portion 5lo lhen the parte are folded or bent along the creases, in the manner shown in Fig. 7, to form the finished carton, the portions of the partition member 5 are bent into a channel or Ushape. rlhe outside ot the intermediate connecting member 5l may be glued to the inside of the top member l to hold it in position, if desired, but this is not a necessity as the bottles or other articles of merchandise which are packed therein will maintain the partitions in position if there is any tendency to shift.

initieel that changes may be made therein without departing from the spirit of my invention.

Again, While l have illustrated my invention as applied to two and three-cell cartons, it is evident that the number of cells may be increased as desired 'and such changes or modifications are intended to be included within the scope of my claims. p

lWhile l have referred to the top, bottom and side members, as .referring to certain designated portions in the drawings, it is to be understood that this is merely Jor convenience in setting forth the construction and that in use the carton may be supported upon any one of these members, any one becoming the top, bottom or side,`

I claim 1. A multicellular carton for bottles and other articles of merchandise, comprising a blank of sheet material having a rectangular body portion provided with parallel creases to form a series of rectangular portions forming the top, bottom, sides and partition of a receptacle, the top beingl formed of two of said rectangular portions separated in the blank by the bottom and side members l and said partition forming an extension of In Figs. 8 and 9 l have shown the inter-v mediate glued seam or joint formed by overlapping the top member l over the inner edge oi" the top member l instead ot having a margin .of the member l bent downward to form a seam flap corresponding to the Hap 6 in Figs l and 2. lt will be understood, however, that either form of in termediate seam or joint may be used. ln this form, shown in'Fig. 9, the inner man gins of the end flaps 4eoverlap and are glued to form a seam or joint and reinforce the seam vextending along the top inthe manner previously described. lt will be seen that the three-cell carton may be collapsed in the same manner as the two-cell i'orm and may therefore be stored and transported in compact form.

l have described in detail the construction disclosed in the accompanying drawings for the purpose of illustrating an embodiment oi my invention, but it will be understood one of said top portions, and end closure flaps connected at opposite ends of each ot said top portions, bottom and side members,

the end flaps on each of the top sections be- A* ing united together to form a unitary end closure for the carton.

2. A multicellular carton for articles of merchandise, comprising a blank of sheet material having a rectangular body creased to form a continuous series of parallel rectangular portions bent to form a closed box or receptacle, the top member being formed by joining the edges of two of said rectangular portions, thereby forming a top member of a single thickness, and having an eX tension projecting from one of said top portions and dividing the receptacle into a plurality of cells or compartments, and end i'iaps projecting from the ends of the sides, top and bottom members of the box, the iiaps on the ends of the top member being `composed of two parts united to the por tions forming said top member.

3. A multicellular carton for articles of merchandise, comprising a blank of sheet material having a rectangular body creased to form a continuous series oil parallel rec tangular portions bentto form a closed boX or receptacle, the top member being formed by permanently uniting the edges of two of said rectangular portions, and end iiaps projecting from opposite ends of said rectangular portions, the flaps on the ends of the top vmember being composed of two parts united together and projecting from the respective portions forming the top member.

4. A multicellular carton, comprising a blank of sheet material having a rectangu- Menem ggg lar body portion provided With parallel end iaps on each of the top sections united 1o creases to form a series of rectangular porto form a unitary end closure for the carton. tions forming top sections, bottom, sides and In testimony whereof li aix my signature a partition member, i:said tlp sectiois being in presence of tWo Witnesses.- f
